Ok, so, one day, i got bored andwent under tools, object maker, and i think i accidentally deleted the cave file. Now i cant add caves to the maps i make! The caves still show up in-game, and in maps i already made, but, if i try loading one of my maps into the map maker, if there was a cave, its not there any more! i was thinking of backing up maps i made, and uninstalling and reinstalling Feral Heart, but i wanted to know if there was a simpler answer to the problem.
